Random House will publish a new spin-off chapter-book series starting in 2015 that picks up where the 2013 blockbuster movie left off. The first two books, “Anna & Elsa #1: All Hail the Queen” and Anna & Elsa #2: Memory and Magic” will both arrive on Jan. 6, 2015, with two more books following later that year. They will be written by veteran author Erica David, with the hopes of “three to four” titles per year.

In a statement, Random House said it was looking to build a fan base akin to their other Disney chapter book series, “The Never Girls.”

“We have seen our Disney “Never Girls” series fill a real niche in the chapter book market, and with the momentum for “Frozen” only continuing to grow, we knew this was the perfect focus for this new series,” said Random House president Barbara Marcus.

The desire to move “Frozen” into a print series isn’t that surprising, after seeing how viable the film and soundtrack have become. The film has grossed over $1.2 billion worldwide and the soundtrack is one of 2014′s biggest-selling albums. Random House has already seen success with a line of “Frozen”-related books designed for younger fans of the film to read with their parents.
